A No. 902,177.'

Be it known that I, ihimrr SCHwOEREiR, a subjectnof the German Emperor, and residing at Strassburg, Germany, have invented certain new and useful .Improvements in Ap- Acid, of which the The present invention relates to an imroved-construction of apparatus or deviceA or carrying out the well-known process for transforming oleic acid into stearic acid un der the action 4of hydrogen'and in the pres-v .ence ofv a lfinely distributed metal, for `instance, nickel,` as catalytic agent.

As described by Sabatier-and Sende-rens in their treatise on the catalytic action of iinely distributed nickel, `(.iifmalesldel Chimie et de Physique, 1905, page 323), the'outp'ut of the roduct riseswith the tem erature. The atter, however, is limited in t e treatment'of oleic acid in lvapor state, since at a temperature of about 27() centigrade the. decom osi'- l tion of the-fatty acids commencesan the generated heavylvolatile products of decom-v position destroy the activity of the contactmaterial. Moreover, the 'irodu'ct thus obtained could notV be use? directly in the manufacture of candles.

It has been found that by carrying out the aboveA described reaction fin the evaporatoritself, the stated'tem erature will not be exceeded and can readl y be controlled by the evaporating medium, thus doing away with the difficulty ofkeeping up the temperature Figs. aand -in' a separate reaction chamber, as well as with thespecial heating and care otherwise' necessar A In ordicr 't0 make my invention readily understood, l will now describe it-with refer.- ence to the accompanying drawing, .in which Figure 1 shows a diagrammatic view of my complete apparatus,.Fi 2 a vertical section throuvhmy improve( ap aratus, and 4 an edge `and a p an view, respectively, of the catalytic mass.

' The process is preferably carried'out in-a' cylindrical receptacle or reaction chamber provided with a helical pan i `which extends perpendicularly from the top to near the bottom of the receptacle, and is supported upon a central post b. l

The oleic acid, gradually heated to a telnerature of from 250-270 C., runs,as is wellown in'the art, down the helical an and is drawn off below.

rectly connected to the iunerwal of the reaction chamber.

According to my invention apply to theA underside. of the helical pan i, the catalytic agent, Vpreferably consisting of an asbestos body lc, containing a copper or the like metal skeleton and suitably impregnated with nickel, as described for instance by Sabatier- Yand Senderens. Opposite the o wermost turn Aof the Worm there is provided the discharge pipe mf.

. C, The employment of the helical pan serves the purpose, unlike theother constructions of Aevaporating chambers, oi effecting' the continuous reaction of thev oleic acid vapor with 'the hydrogen, Without wetting thecat alytic agentv width liquid oleic acid, which would produce tar formation on it and thus disturb perfect reaction.

The arrangement ofthe catalytic mass k is shown in 3. The skeleton is formed. of kwires n, 'n ocopper like the Woof of a fabric.

It servesas binder for the .asbestos threads o serving 'as warp, vwhich accordingto Saba-l tier-and Sendcrens are impregnated withthe catalyte.V

T he operation oi' my yimproved device lis as lfollows: The superheated steam combines with the hydrogen 1n chamber e (Fig. 1) for instance by mixing in the hydrogen continuously.` The fatty acids, entered throu h -pipe C or other suitable inlet and preferab y pre-warmed, arev then dissolved by means of an injector f into small drops., and areth'en conducted through pipe h into the catalytic apparatus g together with .thesuperheated steam and hydrogen. Or .the fatty acids may be introduced into the upper part of the 'helical pan 'i (Fig. 2) in any-other suitable 10's' They are then heated to aI temperature `oi from 25m-270 C. by the regulatablc vheat within the jacket chamber 1,'
